[Nfd-dev] Handling new content in app for pending interest in NFD

[Burke, Jeff]

Hi folks,

We are facing this scenario in a few applications:

1) Interest received by NFD, passed to an application
2) Application not able to respond to interest, so interest stays in NFD PIT
3) Some time passes, but not enough for the Interest to expire
4) Application generates data (e.g., from a sensor reading) that would answer the Interest in the NFD PIT

Question: How does app know to inform NFD it has the data after step 4, and how should it do that?

- In this type of app, should it push the data unsolicited to the NFD and let it decide if there is something to do?
- Is it recommended to implement an application-level PIT so the app is sure this data is solicited?  (Why add another PIT?)

Thank you,
Jeff
